Our Purpose

Mastercard powers economies and empowers people in 200+ countries and territories worldwide. Together with our customers, we’re helping build a sustainable economy where everyone can prosper. We support a wide range of digital payments choices, making transactions secure, simple, smart and accessible. Our technology and innovation, partnerships and networks combine to deliver a unique set of products and services that help people, businesses and governments realize their greatest potential.

Title and Summary

Lead Software Engineer, Lead Architect - Open Finance

Overview
Imagine a world where your ﬁnancial data works for you—securely, seamlessly, and smartly. Mastercard Open Banking is making that vision a reality. By putting control back into the hands of consumers and businesses, we’re redeﬁning how ﬁnancial information is shared and used.

Through trusted, consent-driven connections, our global open banking platform—enables everything from real-time account insights to frictionless payments. It’s not just about access; it’s about empowerment. With secure APIs and a commitment to compliance, we’re building a more inclusive digital economy where innovation thrives, and smarter ﬁnancial decisions are just a tap away.

Innovation doesn’t happen by chance—it’s designed. That’s why architecture is at the core of this transformation journey. As technologies converge and ecosystems expand, our architects ensure every solution is scalable, secure, and built for the future. We are visionaries who transform data into opportunities and translate bold ideas into resilient, real-world systems.

If you're passionate about building what’s next, and thrive at the intersection of strategy, systems, and scale—this is your moment.

Role
As a Lead Architect, you will:

Design and deliver robust, scalable, and secure Open Banking services that power next-generation ﬁnancial experiences.
Be deeply hands-on, diving into code, architecture reviews, and design sessions to ensure technical excellence and execution.
Collaborate closely with product and business teams to shape

what and how of our most critical initiatives.

Mentor engineers and tech leads, raising the bar through coaching, code reviews, and architectural guidance.
Solve the right problems the right way, applying sound judgment and balancing trade-oLs between speed, scale, and sustainability.
Simplify complexity, optimize cost-beneﬁt strategies, and drive architectural decisions that deliver long-term value.
Foster a “can-do” culture, showing bias for action, creative thinking, and a refusal to settle for the status quo.
Engage across teams, identifying reuse opportunities, breaking down silos, and contributing to enterprise-wide architectural alignment.
Lead by doing, not just directing—your technical depth and execution mindset will inspire those around you.

All about you

8+ years of experience in software engineering and architecture, with strong expertise in Java, Spring Boot, Hibernate, and microservices.
Hands-on experience designing and building secure, scalable systems in cloud environments (AWS, Azure, or GCP).
Strong foundation in secure development practices, including cryptography, encryption, and secure communication protocols.
Proﬁciency in secure coding practices in any of modern languages - Java, C#, Python, Node.js and more. Fluency in OWASP, CWE and vulnerability management -write code that’s not just functional - but fortiﬁed.
Proven ability to lead technical initiatives, especially in fast-paced, high-impact environments like Financial Services with a strong understanding of compliance needs and regulatory frameworks.
Excellent collaboration and communication skills, with the ability to inﬂuence, resolve conﬂicts, and align cross-functional teams.
Creative problem-solving mindset, with a passion for continuous improvement and a drive to tackle increasingly complex challenges.
Force multiplier, bar raiser, ownership mentality, and a commitment to delivering high-impact outcomes.
Experience mentoring engineers, conducting technical interviews, and helping build high-performing teams.

Why Mastercard?
This is more than a role—it’s a mission. You’ll be part of a team that’s building the future of Open Finance, where data empowers people, and technology unlocks opportunity. You’ll work with brilliant minds, cutting-edge tools, and a culture that values innovation, integrity, and impact.

Corporate Security Responsibility

All activities involving access to Mastercard assets, information, and networks comes with an inherent risk to the organization and, therefore, it is expected that every person working for, or on behalf of, Mastercard is responsible for information security and must:

Abide by Mastercard’s security policies and practices;
Ensure the confidentiality and integrity of the information being accessed;
Report any suspected information security violation or breach, and
Complete all periodic mandatory security trainings in accordance with Mastercard’s guidelines.
